By bouncing eye-safe laser pulses off mirror on hillside, researchers at NIST have transferred ultra precise time signals through open air with precision equivalent to "ticking" of world's best next-generation atomic clocks. Described in Nature Photonics, demonstration shows how next-generation atomic clocks at different locations could be linked wirelessly to improve geodesy, distribution of time and frequency information, satellite navigation, radar arrays, and other applications.
